New & need help!

Ok, So I'm new to Droid. I recently got a Droid Incredible 2 about 2 weeks ago. This morning I noticed that my contacts and market were not working. I took my phone back to the Verizon store where the "helper" said that I needed to do a factory reset. Before she did this, she moved my apps to my SD card. Now that my market is working again, and I have my contacts back, I cannot access my apps that she "saved". How do I do this? Also, my home Wi-Fi was working before today's reset and now, my phone is not even recognizing that there is Wi-Fi here.
